Notice of the proposed decision will <br />be published as soon as possible. The publication will initiate the ten (10) <br />day public comment period for the Division's decision. <br />CYCC has committed to making the following changes regarding the Hydrologic <br />Monitoring Reduction Technical Revision (TR-02): <br />1) CYCC will continue to monitor Well 008-AV-1 for field parameters. Data <br />collected from 008-AV-1 indicate that the water quality in this well is <br />worse than the quality at 008-AV-2. In order to make accurate material <br />damage and salt loading predictions the Division has requested that this <br />well continue to be monitored. CYCC will submit maps indicating <br />008-AV-1 as part of the Hydrologic tonitoring Program. CYCC has <br />committed to updating the appropriate tables and text. <br />2) CYCC has agreed to reformat Table 2 per the Divisions instructions. The <br />revised table will be submitted with the 1986 Annual Hydrologic Report. <br />If you have any questions please feel free to contact me, at your convenience. <br />Sincerely, <br />~.~~.~~ ~ <br />Brent C.
